ANNUAL 
REPORT 
1954-55 



LOS ANGELES COUNTY 




TO THE PEOPLE WHO VISIT THE ARBORETUM, IT IS MANY THINGS. 

IT'S A LAQOON, ALONG WHOSE SHORE ONE SEES TALL EUCALYPTUS, CLUMPS OF 
PAPYRUS, A BANANA TREE OR TWO, A DENSE WILD GRAPEVINE AS A GROWING MANTLE ON 
THE ASCENDING AND SLIGHTLY BENDING TRUNK OF A PALM. AT TIMES, WHITE WATER 
LILIES GRACE THE SURFACE OF THE LAGOON. WILD BIRDS OF EVERY SORT FIND FOOD 
AND SHELTER IN THE JUNGLE BORDER OR ON THE SURFACE OF THE WATER. IT'S AN EVER- 
CHANGING SCENE OF BEAUTY. IT'S NATURE'S MOST NATURAL CORNER. 

IT'S A SIGHTSEERS MECCA. SUNDAY VISITORS COME FOR AN UNHURRIED RIDE 
ON THE "JEEP" TRAIN TO SEE LIVING PLANTS OR LEARN A LITTLE EARLY CALIFORNIA 
HISTORY OR JOURNEY THROUGH THE PLANT WORLD OF AUSTRALIA, SOUTH AFRICA, OR 
SOUTH AMERICA IN MINIATURE. SCHOOL CHILDREN OF ALL AGES AND THEIR TEACHERS 
USE THE ARBORETUM AS AN OUT-OF-DOOR CLASSROOM. GARDEN CLUBS SEE THE "NEW" IN 
HORTICULTURE. IF FOR NONE OF THE ABOVE REASONS, ONE CAN ENJOY BEAUTY AND 
PEACE OF MIND AWAY FROM THE TRAFFIC AND HUSTLE OF EVERYDAY LIFE. 

PASSIFLORA ALATO-CAERT TT.KA OR THE PASSION FLOWER, SYMBOLIZES THE EXOTIC 
OR UNUSUAL IN FLOWER FORM. NEW AND UNTRIED SPECIES OF EUCALYPTUS, ACACIAS, 
BOTTLEBRUSHES, BAMBOOS, PALMS, AND MANY OTHERS, ARE OFFERED FOR STUDY. BOTA- 
NISTS AND HORTICULTURISTS THE WORLD OVER WATCH WITH INTEREST AND ENCOURAGE- 
MENT THE DEVELOPMENT OF THIS NEW PLANT MUSEUM. 

TO MANY, THE GREENHOUSE AND PLANT RECORDS KEPT THEREIN ARE OF PRIME 
IMPORTANCE. THIS IS THE DOOR THROUGH WHICH EVERY SEED, CUTTING, OR PLANT, 
OFFICIALLY ENTERS THE ARBORETUM. IN ORDER, A SEED IS GIVEN A LIFETIME NUM- 
BER, PLANTED IN THE GREENHOUSE, MOVED TO THE LATHHOUSE, AND FINALLY TRANS- 
FERRED TO THE FIELD. THERE ITS ABILITY TO GROW, FLOWER AND SET FRUIT IN 
SOUTHERN CALIFORNIA IS OBSERVED AND RECORDED. TO DATE, THE GREENHOUSE HAS 
BEEN THE TEMPORARY HOME OF 12,836 PUNTS. BEING ONE OF THE VERY FIRST ALL 
ALUMINUM GLASSHOUSES IN THIS AREA, ITS CONSTRUCTION AND OPERATION IS A SOURCE 
OF STUDY FOR THE NURSERY TRADE. 

LAST, WE SEE THE ARBORETUM LOCATED AT THE VERY FOOT OF OCCASIONALLY 
SNOW CAPPED MOUNTAINS. SUCH A LOCATION IS A VERY REAL CHALLENGE TO PLANT 
INTRODUCTION AND MANAGEMENT. SOUTHERN CALIFORNIA DOES ENJOY SEASONAL CHANGES. 
FOR A PART OF THE YEAR AT LEAST, WE EXPERIENCE SMOG FREE, CRISP WEATHER WHICH* 
EXCITES US TO CONTEMPLATIONS COMPARING OUR OWN SMALLNESS WITH HIS GREATNESS 
IN THINGS NATURAL. 

THE EDITOR 



291 No. Old Ranch Road, Arcadia, California 

July 5, 1955 



Honorable Board of Supervisors 

County of Los Angeles 

Los Angeles 12, California 



It is a pleasure to submit herewith the second Annual Report 
of the Department of Arboreta and Botanic Gardens, County of Los 
Angeles. 

With sincere regrets, the submission of this report will 
terminate my official capacity as Arboretum director for this De- 
partment. It is hoped, however, that in my new capacity as director 
of Longwood Gardens, Kennett Square, Pennsylvania, I may continue to 
share with you a feeling of real accomplishment through the develop- 
ment of a potentially great Horticultural institution. 

In this age of mechanical, chemical, electronic and atomic 
miracles, we need not fear a decline in the powers of nature. Rather, 
that a feeling of closeness to nature through Horticulture and Garden- 
ing shall be one of the potent stabilizers of our civilization. The 
veracity of this statement is fully evidenced by the fact that home 
gardening is the "No. 1" hobby of the American today. In a climatic- 
ally unique area such as you have in southern California, your honor- 
able board may consider with pride, the great part you are contribut- 
ing to the expansion, understanding and enjoyment of ornamental 
horticulture. Through the Arboretum and its program over the coming 
years, every resident of Los Angeles County shall stand to gain cul- 
turally and spiritually a better peace of mind. 

May I take this opportunity of expressing deepest appreciation 
to my staff in whose hands the writing, compiling and assembling of 
the following report will fall, as will the operation of the Arboretum 
until the installment of my successor. I consider it one of the high- 
lights and privileges of my experience to have worked with this 
of men and women who have always looked upon their positions as 
not "jobs" and held the aims of the Arboretum above those of self. 



Respectfully submitted,

DR. RUSSELL J. SEIBERT 

- AN APPRECIATION - 

BY SAMUEL AYRES, JR. 

CONFLICTING EMOTIONS ARE THE ORDER OF THE 
DAY AT THE LOS ANGELES STATE AND COUNTY 
ARBORETUM - REGRET AT THE LOSS OF DR. 
SEIBERT AND PRIDE IN THE FACT THAT OUR 
DIRECTOR WAS CHOSEN ABOVE ALL AVAILABLE 
CANDIDATES IN THE FIELD TO BECOME THE NEW 
DIRECTOR OF LONGWOOD GARDENS, THE FAMOUS 
ESTATE OF THE LATE PIERRE DU PONT, NEAR 
PHILADELPHIA. 



THE RESPONSIBILITY WHICH DR. SEIBERT HAS 

ASSUMED IN HIS NEW DUTIES IS PROBABLY 

GREATER THAN THAT OF ANYONE IN THE FIELD 

OF BOTANY AND HORTICULTURE IN THE HISTORY OF THIS COUNTRY. NOT ONLY WILL HE 

HAVE CHARGE OF FURTHER DEVELOPING THE ALREADY BEAUTIFUL AND FAMOUS LONGWOOD 

GARDENS, BUT HE WILL DIRECT SYSTEMATIC WORLD-WIDE PLANT EXPLORATIONS IN 

SEARCH OF ORNAMENTAL PLANTS (SOME OF WHICH WE HOPE MAY ULTIMATELY LAND IN OUR 




OUR REGRET AT LOSING DR. SEIBERT IS BASED UPON OUR AFFECTION FOR HIM, HIS 
BEAUTIFUL AND TALENTED WIFE AND HIS THREE ATTRACTIVE CHILDREN, AND FOR HIS 
EXCELLENT PERFORMANCE AS DIRECTOR DURING THESE PAST FIVE YEARS. OF PRIMARY 
IMPORTANCE IS DR. SEIBERT f S FRIENDLY PERSONALITY WHICH HAS INSURED CORDIAL 
RELATIONS WITH THE COUNTY BOARD OF SUPERVISORS AND OTHER COUNTY OFFICIALS 
AND WITH ALL MEMBERS OF THE STAFF, THE GOVERNING BOARD AND THE BOARD OF THE 
ARBORETUM FOUNDATION. 

PARALLELING HIS FINE PERSONALITY, DR. SEIBERT »S SCIENTIFIC BACKGROUND HAS 
LAUNCHED THE ARBORETUM ON A CAREER WHICH SHOULD PLACE IT AMONG THE BEST IN 
THE WORLD. A NUMBER OF IMPORTANT RESEARCH PROJECTS HAVE BEEN UNDERTAKEN 
DURING THE PAST FIVE YEARS, SOME OF THEM IN COOPERATION WITH CALIFORNIA 
INSTITUTE OF TECHNOLOGY. ONE VERY PRACTICAL RESEARCH PROBLEM HAS HAD TO DO 
WITH THE STUDY AND PROPAGATION OF FIRE-RESISTANT PLANTS FOR USE ALONG FIRE- 
BREAKS AND IN BURNED-OVER AREAS. THE RESULTS OF THIS RESEARCH PROJECT ARE 
NOW BEING UTILIZED BY THE COUNTY AND NATIONAL FORESTRY SERVICES. 

FINALLY, DR. SEIBERT HAS DIRECTED AN EXTENSIVE PROPAGATION AND PLANTING PRO- 
GRAM ON THE ARBORETUM GROUNDS AND HAS SET THE STAGE FOR A LIVING MUSEUM OF 
BEAUTY AND OF EDUCATIONAL VALUE, A STAGE WHICH IS DESTINED TO BECOME ONE OF 
THE OUTSTANDING SHOW PLACES IN SOUTHERN CALIFORNIA. 

SO WE REGRETFULLY BID DR. SEIBERT A TEMPORARY FAREWELL. WE ARE CERTAIN THAT 
IT IS ONLY TEMPORARY BECAUSE HE HAS PROMISED TO KEEP US ON HIS VISITING LIST 
AND WE BELIEVE HE WILL FIND IT POSSIBLE TO MAKE AVAILABLE TO THE ARBORETUM 
SOME OF THE PLANT TREASURES WHICH HIS TEAMS OF EXPLORERS WILL SEND BACK TO 
THIS "" 



SO LONG, RUSS, AND THE BEST OF LUCK. 



GROUNDS DEVELOPMENT AND CAPITAL IMPROVEMENTS 



THE LOS ANGELES STATE AND COUNTY ARBORETUM HAS JUST PAST THROUGH ANOTHER 
SUCCESSFUL YEAR A YEAR MARKED BY CONSIDERABLE ADVANCEMENT TOWARDS BRING- 
ING INTO LIVING REALITY, MORE AND MORE OF THE MASTER PLAN. 

A BRIEF SURVEY COVERING THE VARIOUS GEOGRAPHICAL AND SPECIAL SECTIONS OF 
THE ARBORETUM WILL INDICATE THAT OUR HORTICULTURAL PROGRAM HAS BEEN CARRIED 
ON TO THE FULLEST PRACTICAL EXTENT WITH THE EXISTING FACILITIES. 



BALDWIN AVENUE ESPLANADE 

THE FORTY FOOT WIDE STRIP ON THE EAST SIDE OF BALDWIN AVENUE, FROM COLORADO 
BOULEVARD SOUTH TO THE RACE TRACK FENCE, BELONGS TO THE ARBORETUM. TWO YEARS 
AGO, WE PLANTED A HEDGE OF CEANOTHUS AND ACACIAS BETWEEN THIS AREA AND THE 
ADJACENT PRIVATE PROPERTIES TO THE EAST. THIS HEDGE IS APPROXIMATELY SIX 
FEET HIGH NOW, AND GIVES PROMISE OF EXCELLENT BLOOM NEXT SPRING. WE'VE RE- 
CEIVED NUMEROUS COMMENTS OF APPROVAL AND REAL PLEASURE FROM THE RESIDENTS 
WHOSE PROPERTY BORDERS THIS PLANTING. 

ON THE WEST SIDE OF BALDWIN AVENUE, FROM COLORADO BOULEVARD SOUTH TO THE 
MAIN ENTRANCE, THERE ARE TWO TYPES OF DECORATIVE AND VALUABLE HORTICULTURAL 
DISPLAY PLANTINGS. 

FIRST, IN THE NORTHWEST CORNER (COLORADO & BALDWIN) IS A COLLECTION OF SPECI- 
MEN ACACIAS. THE STRIKING GLOW OF COLOR PRODUCED BY THE MYRIADS OF YELLOW 
BALLS OF FLOWERS THIS SPRING, RESULTED IN MANY INQUIRIES BY THE PUBLIC FOR 
INFORMATION CONCERNING THE KIND OF PLANTS AND METHODS FOR THEIR CULTURE. 
ALTHO, THIS PLANTING IS BUT TWO YEARS OLD, IT HAS NEEDED THINNING, AND WILL 
AGAIN BE A BEAUTY SPOT NEXT YEAR. 

SECOND, THE DIVIDING STRIP, BETWEEN PARKING LOT AND BALDWIN AVENUE, AND THE 
FENCE LINE AREA JUST WEST OF THE PARK DIG LOT, HAS BEEN ENHANCED BY LOW MAIN- 
TENANCE PLANTINGS. THE DIVERSIFICATION IN PLANT SPECIES OF WIDE RANGE GIVES 
COLOR HERE AND THERE ALONG THE ESPLANADE THROUGHOUT THE YEAR. 

WE'RE JUSTLY PROUD OF THE GARDENER WHO HAS BEEN IN CHARGE OF THIS PARTICULAR 
AREA FOR THE PRIDE HE OBVIOUSLY TAKES IN MAINTAINING THE ATTRACTIVE "FRONT 
YARD" OF THE ARBORETUM. 



AUSTRALIAN SECTION 



GROUNDS DEVELOPMENT AND CAPITAL IMPROVEMENTS - continued 

TREES, INDICATED THAT CERTAIN SPECIMENS GREW MORE THAN SIX FEET IN A SINGLE 

YEAR. WE'VE BEEN A LITTLE SHY OF ADEQUATE WATER LINES IN THIS AREA 500 

FEET OF HOSE WERE NEEDED TO REACH CERTAIN NEW PLANTINGS HOWEVER, THIS 

DID NOT DETER OUR PROGRESS. NEXT YEAR WE FEEL CERTAIN SUCH CONDITIONS WILL 
BE CORRECTED. 

LAST YEAR, THE COLORFUL BOTTLEBRUSH GROUP WAS ALMOST UNNOTICED. THIS YEAR, 
NO ONE CQULD MISS THE LACY, NEEDLE-LIKE FOLIAGE OR THE VIVID REDS, SOFT PINKS, 
THE MAGENTAS, OR WHITE "BRUSHES" (THE FLOWERS) OF THIS COLLECTION. WE HAVE 
LEARNED SOMETHING OF THE WATER REQUIREMENTS OF THESE PLANTS WHILE ENJOYING 
THEIR BLOOMS. 

ANOTHER AUSTRALIAN NATIVE — ANIGOZANTHUS — WAS TRANSPLANTED FROM A FIELD 
NURSERY TO ITS PERMANENT HOME IN THIS SECTION. RE-ESTABLISHMENT WAS RAPID 
AND EXTREMELY SUCCESSFUL. 

THERE IS AN ACACIA COLLECTION INSIDE THE GROUNDS, AS WELL AS, OUTSIDE. SOME 
OF THE MORE RARE SPECIES OF THIS GROUP BLOOMED FOR THE FIRST TIME. RESULTING 
SEED WILL BE COLLECTED FOR OUR OWN USE AND FOR EXCHANGE PURPOSES. 



SOUTH AFRICAN SECTION 

SOUTH AFRICA IS THE HOME OF MANY BRIGHTLY FLOWERING PLANTS BELONGING TO THE 
COMPOSITE FAMILY. A VIGOROUS BEGINNING HAS BEEN MADE IN BRINGING THIS SECTION 
UP TO SUCH COLOR. BOTH WATERING PROBLEMS AND SOIL STUBBORNNESS HAVE PLAGUED 
THIS AREA FROM THE BEGINNING. THE YOUNG ARBORETUM GARDENER IN CHARGE OF THIS 
SECTION HAS DONE VERY COMMENDABLE WORK IN THE INITIAL STAGES OF DEVELOPING 
"SOUTH AFRICA". 



MEDITERRANEAN SECTION 

THIS SECTION IS THE LEAST DEVELOPED AND MOST OBVIOUSLY SO. BUT THERE'S 
AN EXCELLENT REASON. THROUGH A GREATER PORTION OF THIS AREA, THE ARCADIA 
WASH FLOOD CONTROL CHANNEL WILL BE CONSTRUCTED, DURING 1956. WE HAVE TRIED 
TO ADD SOME INTEREST HERE, NEVERTHELESS, BY PLANTING NATIVE CISTUS OR ROCK 
ROSE SPECIES IN SMALL BAYS ALONG THE ROAD EDGE. 



THE SCREECHING OF MONKEYS, THE HOOTING OF OWLS, THE ROAR OF A LION AND 
POSSIBLY A HYENA'S LAUGH ARE SOUNDS OFTEN HEARD FROM THE JUNGLE. TRUELY 
THESE NOISES ARE EXPRESSIONS OF IMAGINATION BY THE CHILDREN TOURING THE ' 



GROUNDS DEVELOPMENT AND CAPITAL IMPROVEMENTS - continued 

JUNGLE. IT'S A FASCINATING, UNIQUE, AND EVER POPULAR SPOT. IT'S THE ONLY 
REAL JUNGLE IN SOUTHERN CALIFORNIA. EACH YEAR, WE ADD SPECIMEN PUNTS OF 
A TROPICAL NATURE — COFFEE TREES, GINGER, SWAMP IRIS, BIRDS-OF-PARADISE, 
BEGONIAS, EPIPHYLLUMS — TO HIGH LIGHT WITH COLOR (ALSO TO TEST FOR HARDINESS) 
THIS AREA LIGHTED IN SHADES OF GREEN. 

APPROACHES TO THE EAST AND WEST ENDS OF THE JUNGLE HAVE BEEN PLANTED WITH 
ADDITIONAL TROPICAL SPECIES THIS YEAR, AND IN TIME THESE PLANTS WILL BECOME 
THE "LOW JUNGLE. 

A SPECIMEN COLLECTION OF ORNAMENTAL GRASSES — PAPYRUS, PAMPUS, LEMON — 
LEAD AWAY FROM THE WEST END OF THE JUNGLE ALONG THE EDGE OF THE LAGOON. 

BAMBOO & PALM SECTION 

SOUTH ALONG BALDWIN AVENUE FROM THE MAIN ENTRANCE OF THE ARBORETUM AND CON- 
TINUING WEST ALONG THE SOUTH FENCE TO THE FOOT OF TALLAC KNOLL, SINOCALAMPS 
OLDHAMI . ONE OF THE TALLER BAMBOOS, WAS PLANTED THREE YEARS AGO TO FORM A 
HEDGE. THIS PLANTING IS RAPIDLY FILLING IN, SCREENING FROM THE ARBORETUM 
VISITOR BOTH HIGHWAY NOISE AND THE WORKING END OF A LOCAL RACE TRACK. 

ADDITIONAL SPECIES OF BAMBOOS AND PALMS (SEE ARBOR WEEK) HAVE BEEN PUNTED 
IN THIS SECTION, INCREASING THE VALUE AND INTEREST OF THESE TWO PLANT TYPES 
WHICH ARE NOT OF THE SHOWY FLOWER VARIETY. 



DOMESTIC LANDSCAPE SECTION 

THIS AREA, PLANTED EARLY IN THE ARBORETUM'S DEVELOPMENT IS BEGINNING TO 
TAKE ON THE LOOK OF MATURITY. PLANTS FROM ALL PARTS OF THE WORLD WHICH 
GIVE PROMISE OF UNDSCAPE VALUE ARE BEING PLANTED TOGETHER. SOME OF THEM 
WILL BE FOUND ELSEWHERE IN THEIR PROPER GEOGRAPHICAL SETTINGS. 

IN THIS AREA ALSO IS A LESSON IN GENETICS COMBINED IN ONE PLANTING. ONE 
PACKET OF SEED PRODUCED BOTH LOW AND HIGH GROWING SHRUBS. A FORM OF ICE 
PUNT . THE FLOWERS OF WHICH BUZE WHEN TOUCHED BY THE BRIGHT SUN. REDS7 
YELLOWS, ORANGE, MAGENTA, UVANDER, AND PINK FAIRLY BLIND THE OBSERVER AT 
NOON. THE MANY PETALLED FLOWERS SEEM COATED WITH A WAXY SUBSTANCE WHICH 
ACCOUNTS FOR THE GLITTER AND SPARKLE. CUTTINGS FROM THESE PLANTS HAVE BEEN 
PUNTED TO FORM LOW BORDERS ALONG THE MAIN ENTRANCE AND SPOTS IN THE MONTH 
BALDWIN PARKING STRIP. 



OLD FASHIONED ROSE GARDEN 



A COMPANION OF THE HERB GARDEN, BUT AS YET VERY EMBRYONIC. 
WILL FEATURE ROSES INTRODUCED PRIOR TO 1905. 




IT MAY WELL BE THAT THE HERB GAR- 
DEN 13 THE "STAR" OF THE ARBOR- 
ETUM THIS YEAR. 



BASIC GRADING WAS 
APRIL AND AS WE REACH THE END OF 
JUNE, THE GENERAL PATTERN IS 
CLEARLY EVIDENT. THE OUTLINE OF 
THE KNOT GARDEN HAS EMERGED AND 
THE KITCHEN GARDEN IS WELL ALONG. 
PRELIMINARY SKETCHES FOR A DIPPING 
WELL IN THE KITCHEN GARDEN HAVE 
3EZN DRAWN A:D THE OUTLINE FOR THE 
MEDIEVAL WALLED GARDEN HAS BEEN 
DEVELOPED. THE HEADERS FOR THE 
PATHS THROUGHOUT THE GARDEN HAVE 
BEEN PUT IN AND THE MAJOR PATHS COVERED WITH CRUSHED ROCK. THE PATTERN AND 
PLAN OF SUCH A DIFFERENT GARDEN WILL, IN ITSELF, STRIKE THE MODERN VISITOR A3 
UNIQUE AND PLEASURABLE: BUT MORE THAN THIS HERE'S A USEFUL BIT OF HORTI- 
CULTURE MUCH REACHES BACK TO TIE VERY EARLIEST OF BOTANY AID PLANT LORE. 
THIS GARDEN IS A LIVING SYMBOL OF MAN'S PROGRESS (HORTICULTUEALLY AT LEAST) 
THROUGH THE AGES. 

WE ARE ALL GRATEFUL TO MEMBERS OF THE SOUTHERN CALIFORNIA UNIT OF THE HERB 
SOCIETY OF AMERICA FOR THEIR WILLINGNESS AND ACTUAL ASSISTANCE IN DEVELOPING 
THIS GARDEN. THEY NOT ONLY SHOULDERED THE FINANCIAL BURDEN OF THE BOXWOOD 
PLANTS, THE REDWOOD HEADERS, AND THE CRUSHED ROCK; BUT IN ADDITION, FURNISHED 
DATA ON THE CULTURE OF HERBS. MISS EDNA NEUGABAUER GAVE US AN OUTSTANDING 
COLLECTION OF LAVANDER SPECIES AND VARIETIES. MRS. A. D. RICHARDSON, 1954-55 
PRESIDENT, HAS DIRECTED THE SOCIETY'S WORK, GIVING CONSTANT ENCOURAGEMENT 
TO THE ARBORETUM COMMITTEE ABLY HEADED BY MISS RUTH RANDALL. WE EXTEND OUR 
SINCERE THANKS TO ALL THE MEMBERS AND LOOK FORWARD TO ANOTHER .FINE YEAR OF 
COOPERATION WITH THE SOUTHERN CALIFORNIA UNIT UNDER THEIR NEW PRESIDENT, MRS. 
CECELIA WILLARD WILCOX. 



TROPICAL GARDEN 

HERE, WE REALLY ARE EXPERIMENTING! IN THIS ABANDONED EARTH RESERVOIR, ATOP 
TALLAC KNOLL, THE CYMBIDIUM3 PLANTED ON THE SLOPING INNER WALL BLOOMED PRO- 
FUSELY THIS YEAR. FURTHER, AROUND THE SIDE, THE SPECIES BEGONIAS IMPART YEAR 
AROUND COLOR. WIRED TO TRUNK AND LIKB, HARDY ORCHIDS AID 3R0MELIAD3 ARE 
BEING TESTED FOR A LIFE OUT-OF-DOORS, UNDER SOME PROTECTION. SOME OF THESE 



GROUNDS DEVELOPMENT AND CAPITAL IMPROVEMENTS - continued 



THE REALLY OUTSTANDING EVENT IN THIS AREA WAS THE LEAFING OUT AND BLOOMING 
OF THE SOUTH AMERICAN TABEBUIAS (SEE ARBORETUM PUBLICATIONS, DR. SEIBERT) . 
IF THESE TREES CAN BE GROWN TO MATURITY, THE ARBORETUM WILL HAVE BROUGHT 
A SPECTACULAR SPLASH OF COLOR AND GRACEFUL BEAUTY TO SOUTHERN CALIFORNIA. 



THIS FISCAL YEAR SAW THE COMPLETION OF THREE PERMANENT BUILDINGS. 1) THE 
HEADHOUSE, CONTAINING A POTTING ROOM, SHOWER AND LOCKER ROOM, PLANT RECORDS 
OFFICE AND UTILITY ROOM WHICH HOUSES THE STEAM GENERATING PLANT USED FOR 
STERILIZING SOIL, POTS, AND OTHER EQUIPMENT. 2) THE PUBLIC RESTROOMS. 3) 
THE FIRST WING OF OUR SERVICE UNIT. THIS UNIT CONTAINS DOUBLE GARAGES, A 
TOOL ROOM, RESTROOM, AND AN ELECTRICAL VAULT. ALL ELECTRICAL AND TELEPHONE 
WIRES ON THE ARBORETUM GROUNDS WILL ENTER FROM THIS VAULT. THESE NEW BUILD- 
INGS HAVE ENABLED US TO INCREASE OUR EFFICIENCY OF OPERATION AND THE PUNTS 
WILL MOVE INTO THE PERMANENT PLANTINGS AT AN EVER INCREASING PACE. 

AS WITH ANY VIGOROUSLY GROWING ORGANIZATION, BUILDING FACILITIES ALWAYS SEEM 
TO LAG BEHIND THE IDEAS AND AMBITIONS OF THE PERSONNEL. ADDITIONAL GREEN- 
HOUSE AND SERVICE SPACE AND EQUIPMENT ARE URGENTLY NEEDED IN SPITE OF THE 
NEWNESS OF THE ABOVE CONSTRUCTIONS.

THE PUBLIC IS UNAWARE OF MUCH OF THE REAL WORK GOING ON IN THE ARBORETUM. 
INCREASE OF OUR PLANT COLLECTIONS IS CARRIED OUT AT A STEADY DAY BY DAY 
PACE, MUCH AS A PLANT ITSELF GROWS. THE FOLLOWING DATA ILLUSTRATES THE 
EFFORTS OF THE PROPAGATION, PLANT RECORDS, AND SECTION GARDEN DIVISIONS 
OF THE ARBORETUM:

IN ACCORDANCE WITH REQUESTS, REPORTS HAVE BEEN FORWARDED TO THOSE INSTITU- 
TIONS ASKING FOR INFORMATION. IN MOST CASES, THESE REPORTS APFLIED TO 
MATERIAL RECEIVED FROM THE UNITED STATES DEPARTMENT OF AGRICULTURE PLANT 
INTRODUCTION GARDENS. WE DID, HOWEVER, FORWARD REPORTS TO OTHER INSTITU- 
TIONS BOTH FOREIGN AND DOMESTIC. 

5. GIFTS 

ALWAYS, THE IMPORTANCE OF A PUBLIC INSTITUTION TO ITS COMMUNITY IS MEASURED, 
IN PART, BY THE GIFTS IT RECEIVES. EACH YEAR, THE ARBORETUM HAS PROSPERED 
THROUGH GIFTS FROM THE CALIFORNIA ARBORETUM FOUNDATION, INC. THEIR DONATIONS 
INCLUDED: ROSES, BEGONIAS, AZALEA HYBRIDS, ORCHIDS, SEEDS, AND VARIOUS 
SPECIMEN PLANTS. 



WEATHER 

DAILY READINGS OF TEMPERATURES, RAINFALL AND EVAPORATION HAVE BEEN RENDERED 
MONTHLY TO THE LOS ANGELES COUNTY FLOOD CONTROL DISTRICT OFFICE FROM THE 
ARBORETUM WEATHER STATION NO. 1037-E. IN ADDITION, WEATHER INFORMATION IS 
GIVEN TO THE CITY OF ARCADIA WATER DEPARTMENT AND ARCADIA CITY HALL. DAILY 
WEATHER REPORTS ARE OF CONSIDERABLE IMPORTANCE TO THE SUCCESS OF PLANT MANAGE- 
MENT. ONE OF THE MANY SERVICES TO THE COMMUNITIES OF SOUTHERN CALIFORNIA IS

SPECIAL PROJECTS 



FIRE RESISTANT PLANTS 

THIS EXPERIMENTAL PROGRAM, STARTED A YEAR AGO, HAS BEEN CONTINUED. THE CISTUS 
OR' ROCK ROSE PLANT WAS STILL THE PRIMARY RESEARCH SUBJECT. TWO PHASES OF WORK 
WERE CONSIDERED. 

FIRST, GERMINATION AND SURVIVAL OF FIELD SOWN SEED. 

IN JANUARY, 1954, TEN CISTUS SPECIES WERE SEEDED ON A FIRE BREAK IN THE MOUN- 
TAINS ABOVE MONROVIA, CALIF. THE FIRST SEEDLING COUNT WAS MADE IN MAY, 1954. 
A SECOND AND THIRD COUNT WAS MADE IN SEPTEMBER, 1954 AND MARCH 1955, RESPECTIVE- 
LY. SEEDLINGS WERE IN EVIDENCE AT EACH COUNT. GROWTH OF THE SEEDLINGS IN- 
DICATED THAT a) SOME HAD SURVIVED FROM THE MAY COUNT: WHILE b) OTHERS HAD 
DIED, BUT WERE REPLACED BY A NEW CROP BETWEEN THE SEPTEMBER AND MARCH COUNT. 

FROM THESE OBSERVATIONS, THE FOLLOWING ASSUMPTIONS SEEM JUSTIFIABLE: 1) CISTUS 
SEEDS WILL GERMINATE UNDER CONDITIONS OF POOR SOIL AND MINIMUM RAINFALL; 
2) FROM A LARGE ENOUGH SEEDING, SOME SEEDLINGS WILL SURVIVE THE RIGORS OF 
FIELD LIFE; AND 3) THE LENGTH OF TIME THAT THE SEED IS VIABLE PERMITS ONE 
SEEDING TO PRODUCE PLANTS FOR MORE THAN ONE SEASON. 

IN ADDITION TO DIRECT SEEDING, THE FLOOD CONTROL DIVISION OF THE U. S. FOREST 
SERVICE IS TESTING TRANSPLANTED SEEDLINGS (SUPPLIED BY THE ARBORETUM) IN 
VARIOUS MOUNTAIN LOCATIONS. OF PARTICULAR NOTE ARE THE PLANTINGS ON THE 
LANNON CANYON EARTH DAM, ARCADIA, CALIF. THESE PLANTS ESTABLISHED A YEAR 
AGO, HAVE THIS YEAR FLOWERED AND PRODUCED SEED. THE RE-SEEDING POTENTIALS 
OF THESE PLANTS WILL BE WATCHED WITH GREAT INTEREST BY BOTH FEDERAL AND 
COUNTY INVESTIGATORS. 

SECOND, A FLUCTUATION IN THE NUMBER OF SEEDS GERMINATING WAS NOTICED DURING 
GREENHOUSE TRIALS WITH CISTUS. IN THE SAME POT OR FLAT OF SEEDS, PERIODS OF 
MUCH GERMINATION FOLLOWED BY PERIODS OF LITTLE GERMINATION, THUS THE TIME OF 
GERMINATION OF A GIVEN LOT OF SEED WAS QUITE EXTENSIVE. AN UNDERSTANDING 
OF THIS PHENOMENA COULD BE USEFUL IN THE ESTABLISHMENT OF CISTUS IN THE FIELD. 
A SERIES OF GERMINATION EXPERIMENTS WERE CONDUCTED. VARIOUS PRE-TREATMENTS 
WERE GIVEN THE SEED. TESTS WERE ALSO ARRANGED AT THE EARHART LABORATORY 
CAL TECH, PASADENA. TO DATE NO CLEAR CONCLUSION CAN BE DRAWN FROM THESE* 
VARIOUS TESTS WHICH WOULD SHED LIGHT ON THIS PECULIAR GERMINATION ACTION. THE 
ONE FACT DEMONSTRATED TO DATE IS THAT CISTUS IS CAPABLE OF GERMINATION UNDER 
EXTREMELY VARIED CONDITIONS. 



FURTHER WORK IS IN PROGRESS. 



SPECIAL PROJECTS - continued 
HERBICIDE TRIALS 



ALNAP-1 (NAUGATUCK CHEMICAL CO.) EFFECTIVE AGAINST SUCK WEEDS AS RAGWEED 
CKICKWEED, ETC., WITHOUT APPARENT DAMAGE TO ZOYSIA MATRELLA, A STOLO- ' 
NIFEROUS GRASS. 

DAIAPON (DOW CHEMICAL CO.) EFFECTIVE ON WEEDS AND GRASSES. KILLED BER- 
MUDA GRASS AT ALL CONCENTRATIONS: SOME BERMUDA REGROWTH AT LOWEST CON- 
CENTRATION OF CHEMICAL. IF CAREFULLY APPLIED THIS CHEMICAL MAY BE USE- 
FUL FOR EDGING BERMUDA GRASS PLOTS, LAWNS, OR GRASS BREAKING THROUGH AS- 
PHALT PAVING. 

PREMERGE (DOW CHEMICAL CO.) A GENERAL WEED KILLER, APPLIED BEFORE EMER- 
GENCE OF CROP PLANT. CAREFUL APPLICATIONS TO PLANT CONTAINERS CHOKED 
WITH YOUNG WEEDS WAS PARTLY SUCCESSFUL REDUCING WEEDING BY HAND. APPLIED 
AS A POST-EMERGENT SPRAY, WEEDS ARE KILLED, BUT REGROWTH IS SOON AP- 
PARENT. 

HERBICIDE AND SOIL STERILANT 

VAPAN (STAUFFER CHEMICAL CO.) IS A NEW SOIL STERILANT AND HERBICIDE 
APPLIED TO PLOTS OF PURE RAGWEED OR PURE BINDWEED, 100^ KILL WAS ACHIEVED 
NO REGROWTH IN THESE PLOTS WAS APPARENT TWO MONTHS AFTER TREATMENT 
TESTS OF SOIL STERILIZATION FOR BOTH POTTING AND CANNING SOIL ARE UNDER 
OBSERVATION. 

A MAJOR DISADVANTAGE OF ALL THE PRESENT WEED KILLERS AND SOIL STERILANTS 
WHICH DIRECTLY CONCERN THE ARBORETUM, IS THAT FEW CAN BE USED AROUND ESTAB- 
LISHED PLANTINGS FOR WEED CONTROL WITHOUT THE FEAR OF DAMAGE TO THE PLANT 
SPECIMEN. 

ALL THE ABOVE CHEMICALS WERE SUPPLIED BY THE MANUFACTURER AS EXPERIMENTAL 
SAMPLES FREE OF CHARGE. THE MANUFACTURER'S NAMES ARE INCLUDED FOR CLARITY 
AND DOES NOT INDICATE ENDORSEMENT OF PRODUCT. 



STUDIES CONCERNED WITH TURFGRASSES FOR THE HOME WERE CONTINUED. THE FOLLOW- 
ING GRASSES ARE GROWING AS PURE PLOTS AT THE ARBORETUM: 

ZOYSIA MATRELLA 445 BERMUDA, EVERGLADES B 

ZOYSIA MATRELLA 1304 BERMUDA J HALL'S U-3

SPECIAL PROJECTS - continued 

CUTTING HEIGHT CHANGE FROM 3" TO 3A" IMPROVED QUALITY OF BOTH THE BERMUDA 
AND ZOYSIA TURFS. IN ADDITION, CLOSE MOWING REDUCED MAT BUILD-UP THUS 
ELIMINATING FALL SCALPING OF THESE LAMS. 

A QUICK METHOD OF PUNTING ZOYSIA MATRELLA PROVED SUCCESSFUL. NO SEED SOURCE 
OF THIS GRASS IS AVAILABLE. VEGETATIVE PROPAGATION IS MANDATORY. SMALL 
SPRIGS OF THIS GRASS TAKE YEARS TO COVER AN AREA. TRIALS HERE SHOWED THAT BY 
SCATTERING QUANTITIES OF SMALL CLUMPS OF STOLONS OVER THE SURFACE OF THE PRO- 
POSED LAWN AREAS, COVERING WITH ONE OR TWO INCHES OF SAWDUST, AND KEEPING 
THE WHOLE AREA WELL WATERED THAT ESTABLISHMENT OF SUCH A LAWN IS POSSIBLE 
GRASS COVERAGE PRODUCED BY SUCH A PROCEDURE IS VERY MUCH ACCELERATED. 

COMPATABILITY TRIALS OF EVERGLADES BERMUDA $2 AND //3 AND HALL'S U-3 BERMUDA 
PLUGGED INTO ESTABLISHED MERION BLUE GRASS TURF, RESULTED IN A COMPLETE RUN- 
OUT OF THE BLUE GRASS IN A LITTLE OVER A YEAR'S TIME. 

THE NEW ZEALAND GRASS, MICROLAENA STIPOIDES . MAINTAINED ITS GREEN COLOR 
THROUGHOUT THE YEAR. IT APPEARS TO BE MORE GREEN DURING THE COOLER SEASONS 
HOWEVER. THIS YEAR'S MAINTENANCE OF THE LAWN AT A l£« CUT APPEARED SUCCESS- 
FUL. CLOSER CUTTING WILL BE ATTEMPTED THIS NEXT YEAR. SEED WAS COLLECTED 
FOR FURTHER TRIALS, BOTH AT THE ARBORETUM AND ELSEWHERE IN THE WEST. 

INFORMATION WAS AGAIN COLLECTED AS TO THE TIME OF YEAR THAT THE VARIOUS 
BERMUDAS AND ZOYSIA TURNED BROWN AND WHEN REGROWTH APPEARED. THESE DATA 
ARE USEFUL WHEN CONSIDERING BREEDING AND SELECTION FOR BETTER GRASS STRAINS 



THE ANNUAL MEASUREMENT OF THE RATE OF GROWTH OF SELECTED TREES AND SHRUBS 
WAS REPEATED. IN MANY CASES, THE INCREASE IN GROWTH WAS CONSIDERABLE OVER 
THE PREVIOUS YEAR'S MEASUREMENTS. THIS WOULD INDICATE THAT THE PLANTS WERE 
SUCCESSFULLY ESTABLISHED IN THE FIELD POSITIONS. THESE AND SIMILAR DATA ARE 
ADDED TO THE INDIVIDUAL PLANT RECORD CARDS WHICH BEAR PROPAGATION AND GROW- 
ING INFORMATION AS WELL. SUCH KNOWLEDGE IS VALUABLE TO BOTH THE HOME OWNER 
AND PROFESSIONAL PLANT3MAN WHEN CONSIDERING LANDSCAPING PROBLEMS USING NEW 
OR UNTRIED PLANT MATERIAL.
